The Club has done all it could to keep Berger, but she has decided to reject our offer of a new deal.
Manager Marc Skinner commented: "I would sincerely like to thank Ann for the contribution she made to Birmingham during her time at the Club.
"She is without doubt a remarkable person and an excellent goalkeeper. Although Ann has chosen a different path I believe she should be remembered for the sheer courage and bravery she displayed both on and off the field.
"On behalf of my staff we wish Ann good health and happiness.
"Now is the perfect time for the Club to show its belief once again in our youth players. Hannah Hampton has the potential to be one of the best goalkeepers in the country. The coaching team will continue to nurture her talents and help her realise her potential."
Berger joined Blues from Paris Saint-Germain in June 2016.
She became an integral part of the team that reached the FA Cup Final (2017) and Continental Cup Final (2016).
A year ago she was diagnosed with thyroid cancer and battled back admirably to resume playing again, in February.
Berger, 28, was named in the WSL PFA Team of the Year at the end of last season and was recently called-up by the German national squad.
Berger made 47 appearances all told for Blues and kept 18 clean sheets, nine of those coming this season across WSL and Continental Cup games.
